KRISS develops moisture detection technology for OLEDs

A technology to measure the level of moisture in OLED displays during the inspection process has been developed by Korea Research Institute of Standard and Science (KRISS).
Due to the high permeability of plastic, the intrusion of moisture into the displays can damage or destroy an OLED's organic material over time therefore reducing the lifespan of an OLED display. Although there is ongoing development to ensure encapsulation methods can be used to mass produce organic electronics that don't allow moisture in, monitoring and measuring moisture levels is still a critical inspection process.
Until now Korean OLED developers have had to rely on foreign technology to measure moisture transmittance during the inspection process. KRISS' new moisture testing technology can transmit the radioactive isotope tritium with a water molecule to a flexible display and measure accurately up to 1/1million g/m2.
